How many of you charge on service calls? We have always done them at no charge unless it required something beyond what was part of the customers normal program and until this year wasn't really ever an issue as I would route the calls with normal treatments within a day or so. Now with fuel prices and the obvious skyrocketing materials debacle I've considered a minimal service charge for service call visits or have the service call scheduled as part of their next treatment if its in the near future. Our service industry is really no different in materials, labor, etc than a plumber, electrician, carpenter, etc and if you call one of them, they aren't going to come out and use their expertise or materials for free. I have seen some in our industry beginning to charge, and wonder what your thoughts are on it. Thanks!
